There really isn't anything mystical about Thai Beads - they're simply designed for delicate anal insertion before intercourse so they can be gently removed during orgasm to send you right off the deep-end with pleasure - and this works for the boys as well as the girls.
You don't have to centre their use around an orgasm, either - they make a great, slow start to anal antics for foreplay or beginners. If you've ever wondered what it's like to properly explore the potential of your body's back-door sexually, then a low-cost set like this can change your world completely.
Being double-ended gives you two sets of bead sizes to choose from - 5 beads at 1.9cm diameter on one end and 5 beads at 2.4cm diameter on the other, all joined by a main line 8mm wide. They're nicely pliable for comfort, and at the same time its firm enough for easy insertion. A great starter set for you or your partner.
